递归代码 [英] Recursive Code
问题描述
我有一个递归函数，但问题是我需要使用
非常大的数据来测试它。总是我的程序进入细分
错误。 RECURSIVE FUNCTION的问题是否附带内存
的事情？改为不递归似乎非常困难。是否有任何
的建议？
I''ve got a recursive function, but the problem is that I need to use a
very big data to test it. Always my program goes to segmentation
fault. Does the problem for RECURSIVE FUNCTION comes with memory
thing? Change to not recursive seems very difficult. Is there any
suggestion for that?

听起来好像你在破坏内存。你可以查看你的程序
与内存检查器如valgrind
Sound like you are corrupting the memory. You can check your program
with memory checker like valgrind
的事情？改为不递归似乎非常困难。那有什么
的建议吗？

你可能用完了堆栈（递归太多）。在调试器下运行你的
应用程序并查看它失败的地方。

You could be running out of stack (too many recursions). Run your
application under a debugger and see where it fails.

是的。我猜它没有堆栈。但我的问题是：太难了
将代码更改为非递归。任何减少使用的建议
堆栈还是重用堆栈？
Yes. I guess it runs out of stack. But my problems are: too difficult
to change the code into non recursive. Any suggestion to reduce use
the stack or reuse the stack?
